A small 0.70-kg box is launched from rest by a horizontal spring as shown in the figure below. The block slides on a track down a hill and comes to rest at a distance d from the base of the hill. The coefficient of kinetic friction between the box and the track is 0.40 along the entire track. The spring has a spring constant of 36.5 N/m and is compressed 30.0 cm with the box attached. The block remains on the track at all times. $30.0 cm-hi ' |-d = '3-l (a) What would you include in the system? Explain your choice. a: This answer has not been graded yet. (b) Calculate d. E _x Your response differs from the correct answer by more than 10%. Double check your calculations. m (c) Compare your answer with a similar situation where the inclined part of the track is frictionless
